Product Description
Features:
Broadband Coverage and High Performance: The SDR transceiver switch antenna sharer (TR switch Box) boasts a wide frequency range from DC to 160MHz, covering multiple communication bands. With a maximum transmit power of 100W, it ensures powerful signal transmission capabilities suitable for various applications requiring high power output. Additionally, its insertion loss is extremely low, less than 0.3dB at 144MHz (typically 0.2dB), ensuring efficient signal transmission and reducing energy loss.
Fast Response and Stable Switching: This device features excellent response speeds, with an ON time of less than 20ms and a release time of less than 190ms, enabling rapid transceiver switching and ensuring continuous and stable communication. This is crucial for applications requiring quick switching of communication states, such as radar systems and emergency communication devices.
Excellent Isolation and Low Interference: In receive mode, the device's isolation is as high as 38dB (typically 40dB) at 144MHz, effectively preventing transmit signals from interfering with receive signals and improving communication quality. This high isolation design allows the device to operate stably in complex environments, reducing the impact of external interference on communication performance.
Safety Protection and Reliable Power Supply: The device is equipped with gas discharge protection, which can effectively protect the circuit in abnormal situations, preventing damage caused by overvoltage or lightning strikes. Additionally, its power supply requirements are 13.8V DC 200mA, easily accessible through common power systems, ensuring stable and reliable operation of the device. This design not only enhances the durability of the device but also reduces maintenance costs.
